RS encoder in DVB-S and some classical decoding algorithms are introduced, then some Fast FourierTransform (FFT) algorithms in finite domain are presented.
The pseudo-spectrum method uses Fouriertransform and finite difference to solve wave equation. It is one of the important methods used to simulate the seismic wave field.
